1 Claim. l

This invention relates to a faller wire control for spinning mules and is a substitute application for application Serial No. 483,196, filed April l5, 1943, now abandoned, for a Spinning mule faller wire control.

It is particularly aimed to provide an instrumentality Which will control the speed of the tension Wire to prevent excess strain on the yarn, and more specically a structure which will avoid the inconvenience and trouble incidental to the breaking down of ends when the faller descends to guide the yarn for winding.

I particularly aim to provide a structure which is exceedingly simple, as a single accurate adjustment eliminates twists at roving rolls due to excess strain ion yarn, one which may be fastened at the front of the mule carriage or the equivalent, one which avoids the use of rods or levers beneath the carriage, and a Structure which requires merely seconds for adjustment.

The more specific objects and advantages will bec-ome apparent from a Iconsideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure l is a fragmentary view in front elevation of a spinning |mule carriage equipped with my improvement;

Figure 2 is a transverse sectional view, fragmentary, thro-ugh a spinning mule carriage showing my improvement in place;

Figure 3 is a View similar to Figure 2 showing the action in the event of breaking down of thread when the faller descends to guide the yarn for winding; and

Figure 4 is an enlarged vertical sectional view, being substantially centrally through my improvement and the adjacent part of the mule carriage.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, It represents a fragment of a conventional spinning mule carriage. I I is a front frame member. The yarn spindles are shown at I2, the faller wire being at I3, with which the faller ill is associated and which is carried by the counter fall-er rod or shaft I5, mounted for rocking as usual.

In carrying lout my invention I provide a unit having an attaching base or bracket at I6 equipped with a vertical flange I1 adapted to be bolted or riveted at I8 to the said frame member II. Such bracket I6 forms the bottom of cylinders I9 and 2t, preferably welded thereto as shown and which cylinders are in communication adjacent the top by a conduit 2I and in communication at the bottom by a pipe or conduit 22 whose ends are mounted by the bracket I6 and which pipe or conduit 22 has an adjustable valve 23 connected therein to close the same or to vary the passage of fluid from one cylinder to the other, and which fluid is for instance cylinder oil.

Screw-threaded caps 24 are removably applied to the tops of the main and auxiliary cylinders I9 and 20. A suitable piston coacts with the main cylinder I9, having a head 26 therein and a stern or rod 21 slidably mounted through the cap 24, specically through a stuiing box 28 thereon.

A collar or the like 29 is mounted in xed position on the rod 21 and a link 30 is pivoted at 3| to the collar and at 32 to a crank 33 extending rigidly from the faller shaft I'5.

The cylinders I9 and 20 are usually about twothirds full of the cylinder oil O, and a icoil spring 35 surrounds the rod 21, resting on the stuffing box 28 and normally at the limit of expansion in the position shown in the drawings and bearing against an abutment collar or the like 34 detachably connected to the rod 21, so that the spring 35 will tend to maintain the piston in and urge it to the position shown in the drawings.

In the event that the faller wire I3 breaks, the faller shaft I5 will rock from the normal raised position of Figure 2 to the position of Figure 3 forcing the piston 26 down in the main cylinder I9, which forces the oil or fluid from the latter into the auxiliary cylinder 20. The action of the faller wire is controlled by the adjustment of the valve 23 since it controls the ow of oil between the main and auxiliary cylinders. Spring 35 returns the piston 26 and the nod 21 to normal position.

Various changes may be resorted to provided that they fall within the spirit and scope of the invention.

We claim as our invention:

In a mechanism of the class described, a bracket including a support-engaging portion and an outstanding horizontal plate, a pair of vertically disposed cylinders open at their upper ends and each having its lower end rigidly secured to and closed by the plate, removable caps for the upper ends of said cylinders, a conduit having ends mounted through the plate and communicating with lower ends of the cylinders, said cylinders containing a volume of fluid, a valve interposed in said conduit and controlling flow of fluid between lower ends of the cylinders, an unobstructed REFERENCES CITED The following references are of record'in the le of this patent:
